Mr. Beale, I understand that. All I'm trying to say is that the figure of minus 49 megatonnes could be equally plausibly minus 4 megatonnes under the rules that have been established, if everybody chose to exercise the options as I've described.
Furthermore, it would seem that a most conservative estimate of the likely increase of oil sand production, hence megatonne production, between 2006 and 2010, could equally be up by as much as 29 megatonnes. In other words, if you took the entire industrial picture and subtracted your 4 megatonnes from your 29 megatonnes, we could be up by as much as 25 megatonnes in 2010. That is not an implausible figure.
